Last Boss Password

At the password screen, press Left 5 times, Down 1 time and enter the Japanese character. Press Right 1 time and enter the Japanese character. Press Right 1 time again and enter the Japanese character. Now, enter the same set of 3 Japanese characters four more times (for a total of five times) and select End.
If entered correctly, you'll appear just two floors away from the last boss in RPG mode.
